[72.02] CCD Imaging of the Open Cluster NGC 3293

R. Slawson, Z. Ninkov (R.I.T.)

CCD images of the galactic open cluster NGC 3293 have been
obtained to study its IMF and star formation history.

This cluster is interesting in that its IMF has been
reported to differ from the usual ``universal'' IMF.
In his review, Scalo (1986) remarks that this is the
youngest cluster with a clear dip in its IMF near
m=3M_ødot.
Herbst amp; Miller (1982) also report an age spread amongst
the member stars and suggest that the IMF varied with
time during cluster formation.

We obtained images both of the center and outer regions
of the cluster in broad-band UBVRI and a narrow-band
filter near the Mg 'b' line.
Here we report on progress in analyzing these images towards
the goal of further studying the IMF of this cluster.
